When a Formula 1 driver is traveling at over 300 km/h, they must be informed of the condition of the track and any potential hazards. That is why the International Sporting Code, which covers all FIA competitions, including Formula 1, defines ten flags and various signs that can be presented to drivers.
When a driver spots a splash of color at the edge of the track, the race can change in an instant. From the iconic checkered flag that signals the finish line to the discreet orange disc that warns of a damaged car, each flag is a language of safety and order that governs every lap of a Formula 1 weekend.
Checkered flag – The ultimate signal indicating the end of a race or practice session. As soon as the black and white flag is waved, the competition stops, even if the flag is premature. During qualifying, a driver who has already started their lap may finish it, but as soon as the flag drops, the session is over.
Yellow flag – A warning signal indicating a problem on the track. A single yellow flag waved indicates to drivers to slow down and avoid danger, whether it is on the racing line or off it, and also covers problems occurring at the start. The double yellow flag raises the stakes: a more serious hazard, the possible presence of marshals on the circuit, and the requirement to slow down “considerably.” Since the 2016 incident in Budapest involving Nico Rosberg, a double yellow flag requires drivers to abandon any qualifying lap in progress. Overtaking is prohibited under any yellow flag until the green flag reappears. Green flag – The signal indicating that the danger has passed. When the green flag is raised, the race resumes normally after a yellow flag period.
Red flag – Reserved for the most serious interruptions: major accidents, debris scattered on the asphalt, or weather conditions that threaten driver safety. The race director alone decides when to deploy it. Red flags appear more often during practice sessions, allowing track marshals to clear the track safely.
Red and yellow striped flag – A static sign warning of reduced grip, usually caused by oil or water. If the slippery conditions become uncontrollable, a red flag replaces it. Blue flag – The dreaded “make way” signal. It appears when a faster car, usually one lap ahead, is approaching a slower driver. After three blue flag zones without yielding, a penalty is imposed. During qualifying, the blue flag warns a driver that a faster competitor is about to overtake them, particularly when one car is on a fast lap and another is slowing down. A stationary blue flag at the pit exit signals that a car on the track is approaching the pit lane. Black and white flag – Reintroduced in 2019 as Formula 1's “yellow card.” It warns a driver of an illegal or unsportsmanlike act, such as braking outside the track limits or exceeding them. Orange disc on a black background – Waved by marshals to indicate that a car is damaged and must return to the pits immediately. This flag usually appears when a defect threatens to detach parts, creating a real safety hazard. Black flag – The most severe penalty. When waved, it orders a driver to leave the pit lane and stop racing, reflecting the decision that the competitor's behavior is dangerously illegal. White flag – Signals the presence of a slow vehicle on the track, such as an ambulance or a car suffering from a serious mechanical problem. It should not be confused with the white flag used in NASCAR or IndyCar to indicate the final lap. Safety Car and Virtual Safety Car signals – The SC signal appears when a physical safety car is deployed; drivers must maintain a prescribed speed and line up behind it. Once the track is clear, any driver who has lost a lap may pass the safety car to rejoin the leaders. The VSC flag introduces a virtual safety car, used for less serious hazards; drivers maintain a set time gap, preserving positions while the incident is dealt with.
